Question

How can I get some data from the tag of a xml file?

I have a tag like this:

`<link href="http://127.0.0.1:8580/directory/playlists/" rel="alternate" type="application/atom+xml;type=feed" />`

I would like to save the http link: http://127.0.0.1:8580/directory/playlists/

Can I use the NSXMLParser?

Thanks a lot!

You need to implement a delegate for the NSXMLParser that conforms to the NSXMLParserDelegate protocol. In this implementation implement at least this method:

-(void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName 
                                       namespaceURI:(NSString *)namespaceURI 
                                      qualifiedName:(NSString *)qualifiedName 
                                         attributes:(NSDictionary *)attributeDict
{
    if ([elementName isEqualToString:@"link"]) {
        NSString* href = [attributeDict objectForKey:@"href"];
        // Do you stuff with the href
    }
}
